1 over 15 x 3 over 2 (after turning them into improper fractions)
this is then: 2 x 45 over 30 ( as it is the common demoninator)
2 x 45 is 90, so this is 90 over 30, which is two
Therefore 1 over 15 x 3 over 2 is two.

Multiplying fractions and mixed numbers?
can't do it as is... you must convert the mixed number to an improper fraction to multiply To convert the mixed number to a fraction you multiply the denominator and the number in front and then add that to the numerator then you put that number over the original denominator ex. 2 1/3 = (3 x 2 + 1)/3 =7/3 then you can multiply: 7/3 X 4/5 = 28/15
What three numbers can you multiply to get 48?
1, 2 & 24 or 1, 3 & 16 or 2, 3 & 8 etc
What is two divided by three fifths?
(2)/(3/5) correct? Well let's remember the laws of multiplying and dividing fractions. To divide a fraction you take the reciprocal and multiply. Let's use this here. Also remember that a whole number is the same as that number over 1 to make it a fraction. For instance in this case we will say 2 = 2/1 making the actual problem (2/1)/(3/5) Now we take the reciprocal of 3/5 (which is 5/3 because (3/5) * (5/3) =1) and multiply by it making the problem (2/1) x (5/3) Now multiply the top times the top and the bottom times the bottom and you get (2*5)/(1*3) =10/3 There's the solution 10/3
Solve 2x-3y4 and x 4y 3 by matrix method?
2x - 3y = 4 x + 4y = 3 Write the augmented matrix: 2 -3 4 1 4 3 Multiply the first row by 1/2: 1 -3/2 2 1 4 3 Subtract the second row from the first row: 1 - 3/2 2 0 -11/2 -1 Multiply the second row by -2/11: 1 -3/2 2 0 1 2/11 Multiply the second row by 3/2 and add it to the first row: 1 0 25/11 0 1 2/11 Thus x = 25/11 and y = 2/11 Check:
What is 3 divided by 1 over 5?
To divide by a fraction, multiply by its reciprocal. In this instance, 3 / 1/5 = 3 x 5 = 15
What is 3 over 2 divided by 8 and 1 half?
it is 3 over 32 (you have to cross multiply them)
What is the answer for 2 over 5 times 1 and 1 over 3?
You change 1 1/3 into a mixed number and then multiply. 2/5 times 4/3 Answer= 8/15
What is one over three multiply six over twelve?
1000,000,000,000,000,000,00,000 * * * * * 1/3 * 6/12 = 1/3 * 1/2 = 1/6
What is the fraction 2 over 3 times 1 over 6?
multiply numerators and denominators , then reduce fraction 2/3 times 1/6 = 2/18 = 1/9
How do you solve a fraction number that is being divided by a whole number?
the easiest way to do do it is to multiply it if it's 1/3 2 the 2 is actually 2/1 so you flip it over and multiply it so it's 1 * 1= 1 3 * 2 =6
What is 3 divided by 1 over 3?
you switch i over 3 to 3 over 1 and then you multiply across
2 over 3 divided by 5?
2/3 divided by 5 become 2/3 multiply 1/5 which is equal to 2/15
How do you find a in the equation 1 over a - 5 over 3a equals 1 over 3?
From the question, I think this is the equation: (1/a) - (5/3a) = 1/3 I'll take this slow. First, multiply both sides of the equation by 'a': (1) - (5/3) = a/3 Now multiply both sides by 3: (3) - (5) = a a = -2
How do you multiply a mixed number with a whole number?
It helps if you change the mixed number into an improper fraction. After you do that you can multiply the improper fraction and the whole number. **hint if you put the whole number over 1 it will make it easier to multiply For example: Multiply 3 and 1/2 by 8 1) change 3 and 1/2 to an improper fraction. It would be 7/2 2) put 8 over one in a fraction. It would be 8/1 3) multiply 7/2 by 8/1 - first multiply the numerators 7 x 8= 56 - second multiply the denominators 2 x 1= 2 4) reduce your answer (56/2) It would be 28 And that is how you multiply a mixed number with a whole number
What is 1 over 2 times 3 over 4?
1 3 / x / 2 4 Multiply the numerators and then the denominators Numerators: 1x3 =3 Denominators: 2x4 =8 So the answer is 3/8 which is 3 ovr 8
What is the solution of 1 equals negative 2 over 3x?
1 = -2/3x Multiply both sides by x x = -2/3
When do you divide fractions?
You flip them over and multiply them as for example 3/4 divided by 1/2 becomes 3/4 times 2/1 = 6/4 = 3/2 or 1.5
